Hi Tateo,
After checking with the designer I am sorry to inform you that we do not have the TINA model available for UCC28700.
I understand it is important for the customer to understand the behaviours of the device before making their own board…

Thanks for your question. I have a few questions to allow me to better understand what's going on.
Is this issue happening with UCC28700EVM-068 ? Did you make any modifications to the circuit? What's the input voltage and output current during…
Other Parts Discussed in Thread: UCC28700 , UCC28700EVM-068 Hello All
How to test over voltage protection of primary side controller, UCC28700? used UCC28700EVM-068 as example.
Thanks,
NT
Other Parts Discussed in Thread: UCC28700EVM-068 Hi,
Now I'm promoting the UCC2870x that is controller with primary-side regulation to our customer. Then they are asking about accuracy of voltage regulation. In UCC28700EVM-068, it state min/max of Vout…
Hello Rajashekar,
The answer to your question 1 depends on several design factors which in turn depend on the target specifications of the system in which the UCC28700 is to be used. I can't give you a specific answer without this background information…
ucc28911.pdf UCC28700-sluu968a.pdf Hi Yue,
Does your customer need a isolator solution or non-isolator solution ?
if the Iout is only 1A m I'd like to proposal UCC28911 to you which don't need a external MOSFET .
For 5V/1A reference design , we…
hello
In the design datasheet of 25W smps using UCC28700, there you mentioned in the pg no :12 , you have directly taken the turns ratio which are obtained from the part number.
1) Will you please elaborate how to calculate turns ratio and number…

The VS pin also senses the bulk capacitor voltage to provide for AC-input run and stop thresholds, and to compensate the current-sense threshold across the AC-input range…
